The mediating effect of attentional impulsivity between mindfulness and problematic smartphone use.

OBJECTIVE: Problematic smartphone use has been linked to lower levels of mindfulness, impaired attentional function, and higher impulsivity. This study aimed to identify the psychological mechanisms of problematic smartphone use by exploring the relationship between addictive smartphone use, mindfulness, attentional function and impulsivity. METHODS: Ninety participants were evaluated with the smartphone addiction proneness scale and classified into the problematic smartphone use group (n = 42; 24 women; mean age: 27.6 ± 7.2 years) or normal use group (n = 48; 22 women; mean age: 30.1 ± 5.7 years). All participants completed self-report questionnaires evaluating their trait impulsivity and mindfulness and attention tests that assessed selective, sustained and divided attention. We compared the variables between the groups and explored the relationship between mindfulness, attentional function, impulsivity and addictive smartphone use through mediation analysis. RESULTS: The problematic smartphone use group showed higher trait impulsivity and lower mindfulness than the normal use group. There were no significant group differences in performance on attention tests. Levels of addictive smartphone use were significantly correlated with higher levels of trait impulsivity and lower levels of mindfulness, but not with performance on attention tests. Mediation analysis showed that acting with awareness, an aspect of mindfulness, reduces the degree of addictive smartphone use through attentional impulsivity, one of the trait impulsivity. CONCLUSION: Acting without sufficient awareness could influence addictive smartphone use by mediating attentional impulsivity. This supports that executive control deficits, reflected in high attentional impulsivity, contribute to problematic smartphone use. Our findings imply that mindfulness-based interventions can enhance executive control over smartphone use by promoting awareness.

Neural Correlates of Trait Impulsivity among Adult Healthy Individuals.

Objective: : Impulsivity can be observed in individuals with or without mental illness. The discovery of neural correlates responsible for trait impulsivity can therefore help to understand the severity of psychiatric symptoms, personality characteristics and social adjustment. In this study, we aimed to identify the gray matter substrates of trait impulsivity in healthy individuals. Methods: : Seventy-five healthy individuals were enrolled. At baseline, trait impulsivity was assessed using the Barratt Impulsiveness Scale (BIS) and all participants underwent T1-weighted magnetic resonance imaging scan. Beck Anxiety Inventory (BAI), World Health Organization Quality of Life (WHOQOL-BREF) and Connor-Davidson Resilience Scale (CD-RISC) were also assessed. Mean cortical thickness (CT) and the local gyrification index (LGI) were calculated to perform whole-brain vertex-wise correlation analysis, which were performed to investigate the relationship between BIS scores and CT or LGI in each brain region. We also revealed the relationship between brain regions and psychological measurements. Results: : Total BIS scores were significantly and negatively correlated with mean CT values in the left lateral occipital cortex (OC) and LGIs in the inferior frontal gyrus (IFG). Correlation analyses revealed that the lateral OC's mean CT values were negatively correlated with BAI scores and positively correlated with WHOQOL-BREF scores, while LGI in the IFG was positively correlated with CD-RISC scores. Conclusion: : Our study showed that trait impulsivity might be associated with the lateral OC and IFG in healthy individuals. Understanding the neural correlates of trait impulsivity could provide ways to expect high impulsivity, anxiety, and poor resilience in healthy adults.

Attention-deficit/hyperactivity disorder combined subtype exacerbates opioid use disorder consequences: Mediation by impulsive phenotypes.

BACKGROUND: Attention-deficit/hyperactivity disorder (ADHD) is highly prevalent and associated with opioid use disorder (OUD). Yet, little is known about the mechanisms by which ADHD (which is a heterogeneous construct/diagnosis) might alter the trajectory of OUD outcomes in persons who use heroin. AIM: We examined whether ADHD subtypes are related to heroin-use consequences and the extent to which the effects of ADHD on lifetime heroin-use consequences are mediated by two impulsivity factors that may be partly independent of ADHD: foreshortened time perspective and drug-use impulsivity. METHODS: Individuals who reported regular heroin use (N=250) were screened using the Assessment of Hyperactivity and Attention (AHA), Impulsive Relapse Questionnaire (IRQ), Stanford Time Perception Inventory (STPI), and a comprehensive assessment of lifetime and current substance use and substance-related consequences. This secondary analysis examined whether ADHD or intermediate phenotypes predicted heroin-use consequences. RESULTS: Relative to participants whose AHA scores indicated lifetime absence of ADHD (n=88), those with scores indicating persistent ADHD (childhood and adult, n=62) endorsed significantly more total lifetime heroin-use consequences despite comparable heroin-use severity. Likewise, there was a significant indirect effect of the combined ADHD subtype in childhood on lifetime heroin-use consequences. This effect was mediated by STPI scores indicating less future (and more hedonism in the present) temporal orientation and by IRQ scores indicating less capacity for delaying drug use. CONCLUSION: The combined ADHD subtype is significantly associated with lifetime heroin-use consequences, and this effect is mediated through higher drug-use impulsivity (less capacity for delay) and lower future temporal orientation.

Borderline personality disorder and aggressive behavior: A study based on the DSM-5 alternative model.

INTRODUCTION: Unplanned reactive aggressive acts are a clinical feature of particular interest in patients with borderline personality disorder (BPD). The early identification of personality traits correlated to aggressive behavior is certainly desirable in BDP populations. This study analyzes a clinical sample of 122 adult outpatients with BPD referred to Adult Mental Health Services of the Department of Mental Health of Bologna, in Italy. METHODS: The study examines the relationship with personality facets of the DSM-5 alternative model for personality disorders (AMPD), Personality Inventory for DSM (PID-5), with respect to the four main components of aggression measured by the Aggression Questionnaire (AQ): hostility, anger, verbal and physical aggression. Using robust regression models, the relationships between PID-5 facets and domains and the aggression components under consideration were identified. RESULTS: Verbal and physical aggression in our sample of BPD outpatients is mainly associated to PID-5 antagonism domain. Physically aggressive behavior is also related to callousness facet. CONCLUSIONS: The traits most consistently associated with aggression were the domain of Antagonism and the facet of Hostility. The study findings highlight the need for clinicians working with individuals with BPD to pay particular attention to traits of hostility, callousness, and hostility to understand aggression.

Impulsive Decision-Making, Affective Experiences, and Parental History of Self-Injurious Thoughts and Behaviors within Parent-Adolescent Dyads.

Impulsive decision-making, particularly during states of affective intensity, is associated with greater risk of engagement in self-injurious thoughts and behaviors (SITBs) during adolescence. The proximal (dyadic parent-adolescent affect and impulsivity) and distal (family history of SITBs) risk factors that occur within the family system could be relevant processes at stake in the intergenerational transmission of risk. The current study tests the interdependence of parent-adolescent factors associated with risk for SITBs and probes the extent to which parent-adolescent affective states influence their own (actor-effects) and each other's (partner-effects) impulsive decision-making, and further whether these relationships are moderated by a parent's history of SITBs. Participants included 212 (106 dyads) community parents and their adolescents who completed self-report and behavioral tasks related to positive and negative affective states, impulsive decision-making, and lifetime history of SITBs. Application of the Actor-Partner Interdependence Model (APIM) revealed a partner-effect where greater parent negative affect in the past week was associated with elevated adolescent impulsive decision-making among families with a history of SITBs (Estimate = 0.66, Standard Error = 0.13, p < 0.001). In addition, a significant actor-effect was observed where greater positive affect was associated with decreased impulsive decision-making among adolescents (Estimate = -0.21, Standard Error = 0.10, p = 0.03), however, moderating effects of parent history of SITBs were not detected. Findings from the present study shed light on the interdependence of affect and impulsivity within parent-adolescent dyads, and the extent to which these interactions may be particularly salient for families with known vulnerabilities for SITBs.

Weight loss impacts risky decisions in obesity.

BACKGROUND & AIMS: Risky decision making is shaped by individual psychological and metabolic state. Individuals with obesity show not only altered risk behavior, but also metabolic and psychological abnormalities. The aim of the present study was to investigate whether a substantial weight loss in individuals with severe obesity will 1) normalize their metabolic and psychological state and 2) will change their pattern of decision guidance. METHODS: We assessed the effect of glycated hemoglobin (HbA1c) and mood on risk behavior in individuals with obesity (n = 62, 41 women; BMI, 46.5 ± 4.8 kg/m2; age, 44.9 ± 14.7 years) before and after 10-weeks weight loss intervention. RESULTS: Results showed that this intervention reduced participants' risk behavior, which was significantly predicted by their changes in BMI. Before intervention, mood, but not HbA1c significantly predicted decisions. After the weight loss, mood no longer, but HbA1c significantly predicted decisions. CONCLUSION: Our findings shed light on the psychological and metabolic mechanisms underlying altered risky decision making in severe obesity and can inform the development of strategies in the context of weight loss interventions.

Impulsivity profiles across five harmonized longitudinal childhood preventive interventions and associations with adult outcomes.

This study aimed to parse between-person heterogeneity in growth of impulsivity across childhood and adolescence among participants enrolled in five childhood preventive intervention trials targeting conduct problems. In addition, we aimed to test profile membership in relation to adult psychopathologies. Measurement items representing impulsive behavior across grades 2, 4, 5, 7, 8, and 10, and aggression, substance use, suicidal ideation/attempts, and anxiety/depression in adulthood were integrated from the five trials (N = 4,975). We applied latent class growth analysis to this sample, as well as samples separated into nonintervention (n = 2,492) and intervention (n = 2,483) participants. Across all samples, profiles were characterized by high, moderate, low, and low-increasing impulsive levels. Regarding adult outcomes, in all samples, the high, moderate, and low profiles endorsed greater levels of aggression compared to the low-increasing profile. There were nuanced differences across samples and profiles on suicidal ideation/attempts and anxiety/depression. Across samples, there were no significant differences between profiles on substance use. Overall, our study helps to inform understanding of the developmental course and prognosis of impulsivity, as well as adding to collaborative efforts linking data across multiple studies to better inform understanding of developmental processes.

Impulsivity mediates the association between narcissism and substance-related problems beyond the degree of substance use: a longitudinal observational study.

BACKGROUND: Narcissism has been implied as a putative risk factor for substance use disorders (SUDs). However, previous research did not disentangle the degree of substance use from substance-related problems, the symptoms of SUDs. This preregistered study addressed the open question whether grandiose and vulnerable narcissism and their constituent traits convey specific SUD risk, that is, explain substance-related problems beyond the degree of use. Furthermore, we tested whether impulsivity or substance use motives linked to narcissistic self-regulation mediate this association. METHODS: Narcissism, impulsivity, substance use motives, past-year substance use, and substance-related problems were assessed in 139 (poly-)substance users, 121 of whom completed a one-year follow-up. For significant longitudinal associations between narcissism factors and substance-related problems controlled for the degree of use, we tested impulsivity and substance use motives as mediators. RESULTS: Grandiose narcissism (r =.24, p =.007) and its constituent factors antagonistic (r =.27, p =.003) and agentic narcissism (r =.18, p =.050), but not vulnerable narcissism, prospectively predicted substance-related problems beyond the degree of substance use. Associations of grandiose narcissism and antagonistic narcissism with substance-related problems were fully mediated by impulsivity, but not substance use motives. Impulsivity explained roughly one third of the association of both grandiose (P̂M = 0.30) and antagonistic narcissism (P̂M = 0.26) with substance-related problems. DISCUSSION: We demonstrate that grandiose narcissism- particularly antagonistic but also agentic narcissism- is specifically linked to substance-related problems beyond the degree of substance use. The mediating effect of impulsivity but not substance use motives suggests that impulsivity may be a more important mechanism than narcissistic self-regulation in promoting SUD in narcissism. However, future studies may use more targeted measures than substance use motives to further probe the role of self-regulation. Similar result patterns for alcohol compared to all substances together indicate that mechanisms may be alike across substances. In conclusion, narcissistic individuals may not use substances more but have a higher SUD risk, informing prevention and treatment.

Understanding the dark side of personality in sex offenders considering the level of sexual violence.

This study examined the relationship between the actual level of physical violence in sexual offenses and dark triad, empathic and impulsive personality traits of their perpetrators. Sixty-four male perpetrators of sexual offenses without any serious mental illness were included. A 5-point Likert-type coding system based on Violence Profile for Current Offense was applied to assess the severity of physical violence of each sexual offense. Personality traits of dark triad (psychopathy, Machiavellianism, narcissism), trait empathy and impulsiveness were also evaluated. Multivariate analyses indicated that non-stranger victim, secondary psychopathy, narcissism and empathy could significantly predict greater involvement of physical violence in a sexual offense. In addition, empathy was negatively correlated with all dark triad traits. Sexual violence should be conceptualized in the form of a continuum, and, considering such an approach, offenders with high secondary psychopathy and narcissism may show preference for sexual assaults that are more violent in nature.

Impulsivity Dimensions Predict Treatment Dropout Among Women in Residential Treatment for Substance Use Disorders.

Residential treatment for substance use disorders (SUDs) is effective at reducing substance use, dependence, and other related problems. However, dropout from treatment against medical advice (AMA) is common in residential treatment settings. Studies have shown that impulsivity is associated with substance misuse and treatment dropout in predominately male samples, but less is known regarding whether impulsivity dimensions predict treatment dropout among women. This study examined impulsivity dimensions (ie, negative urgency, positive urgency, lack of perseverance, lack of premeditation, and sensation seeking) as predictors of dropout AMA among women in a residential substance use treatment facility (N = 229). Logistic regression results demonstrated that elevations in lack of perseverance and sensation seeking were associated with an increased odds of treatment dropout AMA and that lack of premeditation was associated with a decreased odds of treatment dropout AMA. Study findings suggest that early evidence-based interventions for sensation seeking and lack of perseverance may improve retention of women in residential treatment.

A pilot study examining hemomania behaviors in psychiatry outpatients engaged with nonsuicidal self-injury.

BACKGROUND: This study aims to conduct the first-ever evaluation of our previously proposed behaviors of "hemomania" in individuals engaged with nonsuicidal self-injury (NSSI). METHODS: The study encompassed 130 outpatients engaged with NSSI who applied at the psychiatry outpatient clinic. NSSI behaviors were assessed using the Inventory of Statements About Self-Injury, while psychiatric diagnoses were evaluated using the Structured Clinical Interview for DSM-5 Disorders-Clinician Version. Subsequently, participants completed the Depression Anxiety Stress Scale-21 and Short Form of Barratt Impulsiveness Scale. RESULTS: The prevalence of at least one hemomania behavior including seeing blood, tasting blood, bloodletting, and blood-drinking was observed to be 43.1% in individuals with NSSI. When participants were divided into two groups, individuals with hemomania exhibited: (1) a higher incidence of psychiatric comorbidities, increased suicide attempts, and more severe symptoms of depression, anxiety, stress, and impulsivity, (2) higher comorbidity rates of borderline personality disorder, body-focused repetitive behaviors, and dissociative disorders, and (3) elevated frequencies of certain NSSI behaviors, including cutting, biting, needle-ticking, and carving, compared to those without. CONCLUSION: Hemomania could be considered a specific impulse control disorder, characterized by heightened impulsivity and a persistent urge to obtain one's own blood. However, further studies are needed to validate this hypothesis.

Tailoring transcranial alternating current stimulation based on endogenous event-related P3 to modulate premature responses: a feasibility study.

Background: Transcranial alternating current stimulation (tACS) is a brain stimulation method for modulating ongoing endogenous oscillatory activity at specified frequency during sensory and cognitive processes. Given the overlap between event-related potentials (ERPs) and event-related oscillations (EROs), ERPs can be studied as putative biomarkers of the effects of tACS in the brain during cognitive/sensory task performance. Objective: This preliminary study aimed to test the feasibility of individually tailored tACS based on individual P3 (latency and frequency) elicited during a cued premature response task. Thus, tACS frequency was individually tailored to match target-P3 ERO for each participant. Likewise, the target onset in the task was adjusted to match the tACS phase and target-P3 latency. Methods: Twelve healthy volunteers underwent tACS in two separate sessions while performing a premature response task. Target-P3 latency and ERO were calculated in a baseline block during the first session to allow a posterior synchronization between the tACS and the endogenous oscillatory activity. The cue and target-P3 amplitudes, delta/theta ERO, and power spectral density (PSD) were evaluated pre and post-tACS blocks. Results: Target-P3 amplitude significantly increased after activetACS, when compared to sham. Evoked-delta during cue-P3 was decreased after tACS. No effects were found for delta ERO during target-P3 nor for the PSD and behavioral outcomes. Conclusion: The present findings highlight the possible effect of phase synchronization between individualized tACS parameters and endogenous oscillatory activity, which may result in an enhancement of the underlying process (i.e., an increase of target-P3). However, an unsuccessful synchronization between tACS and EEG activity might also result in a decrease in the evoked-delta activity during cue-P3. Further studies are needed to optimize the parameters of endogenous activity and tACS synchronization. The implications of the current results for future studies, including clinical studies, are further discussed since transcranial alternating current stimulation can be individually tailored based on endogenous event-related P3 to modulate responses.

The Structure of Hypersexuality and Its Relation to Impulsivity.

Among the multiple controversies surrounding hypersexuality is the important issue of whether it constitutes a univocal construct. Although an initial study supported its homogeneity, more resent research has identified two separate subcomponents-problematic sexuality and sexual drive. The present survey study addressed this issue in a sample that included both in-person tested college students (n = 69) and online respondents (n = 339). A factor analysis of scales attempting to capture the indicators of each subcomponent of hypersexuality yielded two correlated, but separate factors. Whereas Problematic Sexuality (PS) comprised scales measuring sexual compulsivity, using sex as a coping mechanism, and the negative consequences of sexual behavior, Sexual Drive (SD) was defined by frequent sexual activity, preoccupation with sexual fantasies, a predilection for impersonal sexual behavior, and facile sexual arousal. These two subcomponents of hypersexuality were found to covary with different types of impulsivity, further supporting their discrimination and providing external validation for their differentiation. Contrary to a priori hypotheses, however, PS correlated highly with Callous/Manipulative/Risk-Taking as well as with a predicted Affective Instability/Behavioral Disinhibition factor, suggesting that PS may constitute an equifinality of separate developmental trajectories for those high on both subtypes of hypersexuality.

Impulsivity, self-regulation, and response withholding in university-student drinkers.

This study was designed to determine how impulsivity, self-regulation, and response withholding are related to one another and to university students' drinking behavior. Participants (N = 108) completed measures of impulsivity, self-regulation, and alcohol consumption. In addition, a computerized Go/No Go task and a backward memory task were used to measure participants' behavioral impulsivity and their memory capacity. The aim was to determine whether (a) light/moderate and heavy drinkers would respond differently when the task stimuli were alcohol-related compared to when they were alcohol-unrelated and (b) whether the accuracy of participants' responses was related to their cognitive ability. Compared to light/moderate drinkers, heavy drinkers were low in self-regulation and high in impulsivity. Heavy drinkers and those with lower memory capacity were also poorer at withholding responses on No Go trials. These findings point to personality/cognitive characteristics that influence university students' alcohol consumption.

Competitive Video Game Exposure Increases Aggression Through Impulsivity in Chinese Adolescents: Evidence From a Multi-Method Study.

It is widely known controversies about the results of violent video game increase aggression. However, the role of competitive video games, has received less research attention, and the underlying mechanisms of their influence are unknown. This study aimed to expand the existing literature by systematically exploring the effects of competitive video game exposure on adolescent aggression and the mediating role of impulsivity. In so doing, three types of studies (collectively N = 2919, mean age varied from 13.75 to 15.44 years, with a balanced gender) combining cross-sectional, experimental, and longitudinal approaches, were conducted. The findings consistently show that competitive video game exposure increased adolescents' aggression and impulsivity. Also, impulsivity mediated the correlation and long-term effect of competitive video game exposure on aggression. However, the experimental study did not confirm the short-term mediating effect of impulsivity, which may be related to the type of aggression measured in the study. The results indicate that competitive video game exposure is an important antecedent factor for adolescent aggression, and impulsivity is the key underlying mechanism.

Youth involvement in serious physical violence and political violence: Similarities and differences in risk factors.

INTRODUCTION: Youth involvement in violence and delinquency has received widespread attention in the literature. However, little is known about youth involvement in political violence, especially among youth who live in conflict areas. The current study examined the mechanisms that underlie youth involvement in serious physical and political violence. We explored the similarities and differences in the association between both individual factors (including religiosity and school commitment) and parental factors (including parental control and education), and the two types of violent behaviors. METHOD: A large representative sample of 814 Arab male students from neighborhoods located in East Jerusalem, aged 12-18 years, completed a structured, anonymous, self-report questionnaire. The data was collected between February and May 2019. RESULTS: Over half of the participants reported that they had been involved in political violence (55.1%) or serious physical violence (58.8%) during the previous year. Youth involvement in serious physical violence was positively associated with involvement in political violence. Furthermore, we found that greater parental control and lower impulsivity are associated with lower levels of political and physical violence. School commitment was associated negatively with serious physical violence but not with involvement in political violence. Youth work was positively correlated with involvement in political violence but not in serious physical violence. CONCLUSION: The results of the current study show that Arab youth from East Jerusalem are highly involved in political and serious physical violence. The risk and protective factors identified here should inform the design of specific intervention strategies.

Effects of yoga on impulsivity in patients with and without mental disorders: a systematic review.

BACKGROUND: Yoga can be used as a complementary intervention to conventional treatments, whether pharmacological or non-pharmacological. Sustained practice of yoga can generate a series of benefits for individuals' quality of life and improve their physical fitness. OBJECTIVE: To investigate the potential effects of yoga as an adjunct intervention in conditions involving impulse control issues, such as attention deficit hyperactivity disorder (ADHD), borderline personality disorder, bipolar affective disorder, and substance use disorders. METHODS: We performed a systematic review of placebo-controlled, randomized trials of yoga in patients with impulsivity. PubMed, Web of Science, and Science Direct databases were searched for trials published up to January, 2023. Data were extracted from published reports and quality assessment was performed per Cochrane recommendations. RESULTS: Out of 277 database results, 6 RCT were included in this systematic review. To assess the level of attention and impulsiveness, the following scales were analyzed: Barratt Impulsiveness, UPPS-P Impulsive Behavior scale, Conners' Continuous Performance Test IIª and Conners' Parent Rating Scale-Revised: Long. CONCLUSIONS: Yoga didn't have a significant improvement in impulsivity when compared to placebo. There are many tools to assess impulsivity, but they mean different concepts and domains consisting in a weakness on comparison of yoga effects. PROSPERO REGISTRATION: CRD42023389088.

How Do Anger and Impulsivity Impact Fast-Food Consumption in Transitional Age Youth?

Introduction: Consumption of fast food has been linked to psychiatric distress, violent behaviors, and impulsivity in adolescents. The relationship between eating fast food, anger, and impulsivity has not been widely investigated. The National Consortium on Alcohol and Neurodevelopment in Adolescence community-based cohort consists of 831 youth, half at elevated risk factors for substance use disorders during adolescence, followed annually. Methods: Impulsivity using Urgency, Premeditation, Perseverance, and Sensation Seeking Impulsive Behavior scale from annual assessments was examined in relation to self-reported fast-food consumption frequency and mobile application questions of anger. This study tested the hypotheses that youth anger may be predicted by fast-food consumption frequency and impulsivity using multiple regression, in addition to whether adolescent fast-food consumption frequency may be predicted by anger and impulsivity. Results: Among youth, higher anger levels and impulsivity predicted greater frequency of fast-food consumption, and greater fast-food consumption frequency and impulsivity predicted higher anger levels. Conclusions: This study's longitudinal findings are consistent with those of other studies that have found fast-food consumption and anger associated with impulsivity and also reveal a bidirectional link between anger and fast-food consumption. These results may point attention to food selection considerations for those at risk of anger and poorer psychiatric outcomes.

Comparison of Opioid Use Disorder Patients with and without Problematic Internet Use in Terms of Impulsivity and Attention Deficit Hyperactivity Disorder.

AIMS: This study seeks to investigate ADHD symptoms and impulsivity among individuals diagnosed with Opioid Use Disorder (OUD) who also exhibit symptoms of Problematic Internet Use (PIU). METHODS: The study involved the participation of 360 Opioid Use Disorder (OUD) patients enrolled at an Alcohol and Drug Addiction Treatment Center (ADATC) during the period from October to December 2022. Various assessment tools were administered, including Young's Internet Addiction Scale (YIAS), Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), Barratt Impulsiveness Scale (BIS), and Adult ADHD Self-Report Scale (ASRS). Problematic Internet Use (PIU) was identified by YIAS scores equal to or exceeding 50. RESULTS: The majority of participants diagnosed with OUD showed comorbid PIU with high levels of depression, anxiety and ADHD symptoms. Both BDI and BAI scores showed a significant increase in the PIU group compared to the non-PIU group (p<0.001). Significant differences were observed in BIS Motor Impulsivity, Attentional Impulsivity and Total scores, indicating higher impulsivity in the PIU group (all p<0.001). Additionally, higher ASRS scores were found in the PIU group (p<0.001). DISCUSSION: These findings highlight the importance of addressing PIU and comorbidities in OUD treatment. Interventions targeting ADHD symptoms and emotional well-being may benefit PIU management.

Dimensions of family stress and repetitive nonsuicidal self-injury in adolescence: Examining the interactive effects of impulsivity and emotion dysregulation.

BACKGROUND: Repetitive non-suicidal self-injury (R-NSSI) in adolescence represents a significant risk factor for suicide. Although exposure to family stress is robustly associated with the risk of non-suicidal self-injury (NSSI), studies have not examined the potential mechanisms linking different forms of family stress and R-NSSI. OBJECTIVE: This study examined how unique dimensions of family stress (threat and deprivation) relate to R-NSSI via interactions between impulsivity and emotion dysregulation. PARTICIPANTS AND SETTING: The current sample included 3801 middle-school adolescents (42.2 % girls, Mage = 13.21 years). METHODS: We conducted a two-wave study with 6-month intervals. Participants completed self-report measures assessing family stress, impulsivity, emotion dysregulation, and NSSI. RESULTS: Moderate mediation analyses showed that threat was indirectly associated with NSSI frequency through the interaction of impulsivity and emotion dysregulation in the R-NSSI group and indirectly through impulsivity in the occasional NSSI (O-NSSI) group. Deprivation did not predict subsequent NSSI frequency in either group. CONCLUSIONS: These findings lend empirical support to dimensional models of adversity and suggest that adolescents who experience threat-related family stress may have greater impulsivity and are more likely to report R-NSSI in the context of emotion dysregulation.
